Working with Arrays

Arrays are stored in HashTable strucures, and have the zval type IS_ARRAY. The API functions for creating, destroying and manipulating these structures as variables are documented here and can be found in Zend/zend_API.h

HashTable as Variable API

Prototype

Description

void array_init(zval* pzval)

initializes the variable as a HashTable, setting type and appropriate destructor function for the HashTable

void array_init_size(zval* pzval)

initializes the variable as array_init with a minimum of size buckets

Note:

Do not squint too hard looking for array_destroy: to destroy a variable array you should call zval_ptr_dtor on the variable, if there are no other references to the variable it will result in the array being destroyed.
